Abstract
The present invention provides a disposable body warmer that makes it possible to suppress scattering of moisture contained in the exothermic composition from the outer bag, and thereby ensure a desired exothermic duration of the exothermic composition when the disposable body warmer is kept in an unused state for a long period of time. The disposable body warmer is structured such that an exothermic composition that contains moisture and generates heat by contact with air is enclosed in one or more air-permeable inner bags, which are accommodated in an airtight outer bag. The outer bag comprises two accommodation units that are partitioned from each other and capable of containing the one or more inner bags. The one or more inner bags each comprise at least one enclosure unit capable of enclosing the exothermic composition, and are accommodated in each accommodation unit in a manner such that at least one of the enclosure units is overlaid with another enclosure unit. The outer bag is formed by overlaying two wrapping films with each other, sealing an entire outer peripheral edge, and partitioning the accommodation units by sealing. Further, in the disposable body warmer, Paramete…
